Operative approaches to the lateral and third ventricles are made challenging by their deep position near the center of the intracranial space, complete encasement in neural tissue, curved shape within the cerebrum, variable shape and size in the different lobes, narrow communicating orifices making them susceptible to obstruction, expansile nature allowing them to act as mass lesions, and walls containing important motor, sensory, and visual pathways and vital autonomic and endocrine centers. The lateral ventricles provide deep cavities through which the third ventricle and basal cisterns may be approached. In this chapter, the neural and vascular relationships that provide the basis for optimizing the results obtained with intraventricular operations are reviewed before the individual operative approaches are described. Many of the structures that form part of the walls of the lateral ventricle are also seen in the third ventricle. Both the lateral and third ventricles are intimately related to the deep venous system, and numerous arteries supply the walls of both the lateral and third ventricles.
